I already did A. 89.60 and B.235.60 but not the letter C I do not understand this one.

In April of the current year, Freeman Steel Company transferred Herb Porter from its factory in Nebraska to its plant in Ohio. The company's SUTA tax rates based on its experience ratings are 3.2% in Nebraska and 3.8% in Ohio. Both states base the tax on the first $9,000 of each employee's earnings. This year, Freeman Steel Company paid Herb Porter wages of $20,900; $2,800 were paid in Nebraska and the remainder in Ohio. Compute the following: round your answers to the nearest cent.
